This bird feeder is ideal if you want to help birds survive the harsh winter. It can of course be used all year round. The semicircular frame provides space for several birds. The roof is not fixed, nor are any of the parts of the food dispenser. You can simply move it and fill the column with bird food. The feeding column is very stable thanks to the suction cup on the window sections. You can watch your feathered friends eating from the inside without frightening them.
